This creates a Vortex field.

            - Magnitude
- 
                  Sets the strength of the vortex field. The larger
                        the number, the stronger the force. A positive number moves the
                        influenced object counterclockwise. A negative number moves the object clockwise.
                      
- Attenuation
- 
                  Sets
                        how much the strength of the field diminishes as distance to the
                        affected object increases. The rate of change is exponential with
                        distance; the Attenuation is the exponent. If you set Attenuation
                        to 0, the force remains constant over distance.
                      
- Axis X, Y, Z
- 
                  Specifies the
                        axis around which the vortex field exerts its force.
                      
Distance
            - Use Max Distance 
- 
                  If
                        you turn on Use Max Distance, connected
                        objects within the area defined by the Max Distance setting
                        are affected by the vortex field. Any connected objects outside
                        the Max Distance are not affected
                        by the vortex field.
                      If you turn off Use
                           Max Distance, all connected objects are affected by the
                        vortex field, no matter how far away they are from the vortex field. 
                      
- Max Distance
- 
                  Sets
                        the maximum distance from the vortex field that the field is exerted.
                        You must turn on Use Max Distance for Max
                           Distance to take effect.
                      
Special Effects
            - Apply Per Vertex
- 
                  Sets
                        where the field emanates from the object. If you turn on Apply
                           Per Vertex, each individual point (CV, particle, vertex)
                        of the chosen object exerts the field equally at full strength.
                        If you turn off Apply Per Vertex, the field
                        is exerted only from the average position of the specified points. 
                      If you are using the Attribute
                           Editor, open the Special Effects section
                        to display the Apply Per Vertex attribute. Available
                           for object fields only. TipIf
                           you use a vortex field with a particle object, you can set the Conserve attribute
                           of the particle object to influence of the motion. If you set Conserve to
                           0, the particle object moves in a circular motion. If you set Conserve greater
                           than 0, you get a spiraling motion.
